Abstract
A flipflop has master and slave interconnected through a buffer. The master has its inverters located outside the signal path from input to output, as the buffer provides the driving capability required for both IDDQ-testing and operational use. This configuration enables IDDQ-testing without further circuitry added to the flipflop and reduces propagation delay in the signal path.
